S M I T H , F.Z.S. [Eeceived June 10, 1891.] (Plates XXXIV. & XXXV.) Together with the duplicates from the ' Challenger' collections, transferred last year from Edinburgh to the British Museum, were a number of specimens which had not as yet been examined. Among these five of the following new species from various localities were discovered. The remainder were all dredged off Sydney in 410 fathoms. At this station (164 B), in addition to the new species here described were a number of others, and amongst these several undoubtedly Atlantic forms. As Dr. Murray proposes to publish a special report upon the results obtained at this station, I refrain from further allusion to it. 1. LAMPUSIA (PRIENE) MURRAYI. (Plate XXXIV. fig. 1.) Testa fusifor mis, albida, subtenuis, epidermide crassiuscula, luteo-cinerea, confertimpilusa induta ; anfractus - ? (apice fracto), convexi, sutura profunda obliqua sejuncti, supremi fort iter eancellati, versus ultimum sensim Iceviores, varicibus duobus instructi, ultimus elongatus, antice breviter rostratus, spiraliter costulatus, costulis longitudinalibus obsoletis subcancellatus; apertura ovata, superne et inferne acuminata, intus sordide albida, cum canali longit. totius \ adcequans; labrum expansum, album, extus incrassaium ; columella leviter arcuata, callo nitido induta ; canalis obliquus, profundus, recurvus. Longit. 87 millim., diam. maj. 43 ; apertura cum canali 45 longa, 19 lata. JLab. Station 142. Off the Cape of Good Hope, in 150 fathoms. This species is much more slender than Priene magellanicus (Chemn.), Dillwyn, and has the spire longer in proportion to the aperture. The epidermis also is of a much closer texture and more finely pilose. 2. CORALLIOPHILA WAHLBERGI (Krauss). (Plate XXXIV. fig. 2.) Purpura wahlbergi, Krauss, Siidafr. Moll. p. 118, pi. vi. f. 15.
